50.5525KRBIG1809I2IM - Ax. drill. and mill. head offset, For collet 250 430E (ER25 Ø2-16), with tapered roller bearing, Similar to DIN 1809 drive, External coolant supply, i = 2:1 same rotating direction, inside collet nut,
Article number: 117042Axial drilling and milling head with offset axes
Premium class tooling system for highest production efficiency - Made in Germany
Collet chuck ER25 DIN6499
- Clamping range Ø2-16
- For collet 250 430E
- When tightening the clamping nut, it is essential to counterhold the tool spindle.
- Failure to observe the counterholding may result in damage to the gearbox or drive coupling.
- Maximum tightening torque: 90 Nm
Tapered roller bearings (KR) - extraordinarily loadable.
- Recommended for machining operations with high torques (e.g.: milling operations with large diameters, threading operations, interrupted cut machining)
- Increase of tool life
- Reduction of service intervals
- Simultaneous radial and axial loads can be easily absorbed
